Exercise Ameliorates Dopaminergic Neurodegeneration in Parkinson's Disease Mice by Suppressing Microglia-Regulated Neuroinflammation Through Irisin/AMPK/Sirt1 Pathway.

Although exercise is known to exert anti-inflammatory effects in neurodegenerative diseases, its specific impact and underlying mechanisms in Parkinson's disease (PD) remain poorly understood.
